-- Col 1:9-14
When Jesus openly entrusts to his disciples the mystery of prayer to the Father, he reveals to them what their prayer and ours must be, once he has returned to the Father in his glorified humanity. What is new is to "ask in his name." Faith in the Son introduces the disciples into the knowledge of the Father, because Jesus is "the way, and the truth, and the life." Faith bears its fruit in love: it means keeping the word and the commandments of Jesus, it means abiding with him in the Father who, in him, so loves us that he abides with us. In this new covenant the certitude that our petitions will be heard is founded on the prayer of Jesus.
